Does negate work in TTTF to kill off Poa Annua and Poa Trivialis?
Negate 37WG can only only be used on bermudagrass and zoysiagrass turf. It cannot be used on any cool season turf like tall fescue. Acclaim is the only product we carry that can be used for poa trivialis in fescue. There are few products that we are aware of that will kill the poa annua without also harming the fescue. The only one we are currently aware of is called Prograss. Your other options would be to either spot-treat with a Roundup-type product and then reseed with the fescue in those areas, or you can use a preemergent in the fall to prevent the poa from growing in the first place
